Description

[Detailed Description of the Invention] The present invention relates to a refrigerator equipped with a duct on the back side for guiding waste heat from a condenser or the like.

Generally, for various reasons, refrigerators cover the condenser exposed on the back side with a back plate to make the back side of the refrigerator body flat, and a heat exhaust duct is formed inside. However, if you attach the handle for transportation to the back plate of this type of refrigerator, it will become bulky.
The flat back of the refrigerator body lost its meaning, and there were problems with the structure of the handle.

The present invention solves the above-mentioned problems, and will be described in detail below with reference to the drawings showing an embodiment of the present invention.

In the figure, 1 is the refrigerator main body, 2 is a storage chamber equipped with an evaporator (not shown) that constitutes a refrigeration cycle inside the main body 1, and 3 is a compressor that operates the evaporator and a high-temperature compressor below the main body 1. The machine room is equipped with a condenser 4 that condenses and liquefies refrigerant gas, 5 is a fan motor, and 6 is a fan. When the fan is rotated, air flows through the front grill 7 to outside air, as shown by the solid line arrow in Figure 1. The heat from the condenser 4 is sucked in, and the heat is absorbed from the condenser 4, ascends from the rear of the fan 6 through a back duct 8 installed on the entire back surface of the refrigerator body 1, and passes through the top duct 9 installed on the entire top surface of the refrigerator body 1. It is blown out to the front. And this refrigerator body 1
There is an L-shaped notch extending from the rear of the top duct 9 to the upper side of the back duct 8, and two openings 10 are provided on the left and right, and corresponding to each opening 10 there is a thin wall 11 that is highly flexible and acts as a hinge. A cover 12 made of synthetic resin, such as polypropylene, is installed. The cover 12 has L-shaped claws 13 and I
An L-shaped claw 14 is provided, and an L-shaped claw 13 is press-fitted and fixed to a flange 15 provided on the lower end surface of the opening 10, while a flange 16 provided on the upper end surface of the opening 10 is provided with an I-shaped claw 13. A shaped claw 14 is removably engaged, and the cover 12 completely covers the opening 10 and forms a part of both ducts. Further, 12a is a recess for handing when opening. Inside the cover 12, a carrying handle 17, which is used when transporting the refrigerator main body 1, is fixed to the back surface of the main body 1. Further, 17a is a ventilation hole provided in the handle 17. In such a configuration, when the refrigerator main body 1 is transported, the cover 12 is rotated in the direction of the arrow M as shown in FIG. The installed handle 17 faces the opening 10, and is grasped and carried. Further, after the transportation is completed, the cover 12 is rotated in the direction opposite to the arrow M to return it to a state covering the opening 10 to form a duct.

In this way, the present invention uses the inside of the duct on the back to attach the handle for transportation to the refrigerator body, so the back of the refrigerator body is flat and easy to handle and install, and no special space is required for the handle. Can be easily configured. In addition, since the handle has a ventilation hole, an air path can be secured without being obstructed by the handle for the air flowing inside the duct, and the heat dissipation effect can be maintained.

In addition, we have installed a duct cover that can be opened and closed at the opening of the duct facing the handle, so by opening the duct cover, you can easily transport the refrigerator by holding the handle.Furthermore, by closing the duct cover, you can configure the duct, and from the back is flat, which is preferable in terms of appearance.
